What's my incentive for subsidizing non-work in others?
This is one. We should go deeper into this question. I most certainly would continue doing a lot of the things I do now, but for fun and to progress the state-of-the-art in my field of work. I'd accept higher taxes in compensation for the assurance I will always be able to do what I do best, instead of what someone would pay me to do.
.. to pay taxes for social services.
> I'd accept higher taxes ...
how do you pay for these taxes if you have no job/income?
Nobody is saying that the carrot (personal financial gain) needs to be removed from the equation. Just that everyone is guaranteed some basic level of financial support.
Society already produces enough wealth to cover the expense of UBI. Remember it would replace any other welfare systems in place today.
Personally I think I might take a bit more risk, and choose to do something that I personally believe is of actual value to society rather than please some corporation or VC.
I’ve never seen this math worked out.
Also, some benefits are inherently lumpy. A special-needs or chronically-ill person needs (and receives) resources that wouldn’t be covered by a broad-spectrum UBI.
In both the US and UK over 30% of households are owned outright with no mortgage.
The economy is made up of us, it's not (predominantly) a downtrodden serving a tiny elite.
